FAB Reactor with COOLFloat Media.
The typical FAB process consists of pretreatment like screening followed by one or more FAB tanks, where the degradation process of soluble matter takes place and the final stage of the treatment is normally particle separation. The FAB tank consists of various components such as earators , spray nozzles, bio-media, grids/sieves, and other integral parts, which makes it a complete successful system. The wastewater after primary settling or screening flows directly in to the FAB reactor through pumping or under gravity.
In this system the organic pollutants of wastewater are decomposed with the help of both attached & suspended growth microorganisms. The COOLFloat polypropylene media used as a medium for the attached bio growth occupies around 30-50% of the tank volume. The rest of the portion of the reactor is utilized for suspended growth aeration system. This lightweight media (of density 0.97gm/cc) is in constant circular motion trough out the tank due to diffused aeration system placed at the bottom.
